Observed enhanced emission at higher-order exceptional points in RF circuits
Nicolas Wyszkowski, Arunn Suntharalingam, Max Vitek +3
The Purcell effect -- stemming directly from the celebrated Fermi's Golden Rule -- links the enhanced emissivity of an emitter to the local density of states (LDoS) of a surroundin…
Synthetic Reflectionless Mode Exceptional Degeneracies via Emergent Local Symmetries
William Tuxbury, Lucas Fernandez-Alcazar, Tsampikos Kottos
We propose a new kind of physically realizable exceptional point degeneracies (EPDs) corresponding to synthetic reflectionless modes (SRM). These are solutions of an auxiliary wave…
Optimal Targeted Mode Transport in Complex Wave Environments: A Universal Statistical Framework
Cheng-Zhen Wang, John Guillamon, Ulrich Kuhl +4
Recent advances in the field of structured waves have resulted in sophisticated coherent wavefront shaping schemes that provide unprecedented control of waves in various complex se…
